Reliable 6.7L long block for Ram HD

The 2013 Cummins 6.7L engine is a proven diesel platform engineered for towing, commercial hauling, and long-mileage operation in Ram heavy-duty trucks. Houston Engines supplies both reman Cummins 6.7 and thoroughly tested used Cummins 6.7L options designed to restore OEM torque, smooth power delivery, and long-term durability. Each diesel long block replacement is inspected for cracks, deck flatness, and oiling integrity to support consistent lubrication and cooling. Cylinder heads are pressure-tested and resurfaced to ensure strong combustion sealing. With renewed internal wear components, this diesel engine delivers stable idle, strong pulling power, and dependable 6.7L Cummins reliability under sustained load.

Remanufactured engine assemblies receive complete machining, including torque-plate honing for precise cylinder geometry, resurfaced deck surfaces for proper head gasket sealing, and reconditioned crankshafts to maintain oil pressure and bearing stability.

New pistons, rings, bearings, gaskets, and seals restore OEM compression balance and oil control. Cylinder heads undergo full valve service, guide inspection or replacement, and updated sealing components to handle high heat and towing cycles common in Ram HD use. Each remanufactured engine is verified for compression consistency and oil-pressure stability before release.

Used Cummins 6.7L engines complete compression and leak-down testing, with borescope inspection confirming cylinder-wall condition and ring seal quality. External seals and gaskets are refreshed, and mounting surfaces are inspected for compatibility with Ram 2500 diesel engine and Ram 3500 long block applications. Houston Engines applies strict quality-control standards to reduce downtime and deliver dependable diesel performance for both work trucks and daily-driven vehicles.

Engine Testing Procedures and Warranty Coverage

Each long block is compression-verified and evaluated for consistent cylinder contribution. When applicable, hot-run testing is completed and logged under the unit record for traceability and quality assurance documentation, ensuring every engine meets performance standards before delivery.

Remanufactured engines include extended protection under a structured Cummins warranty program. Used engines include standard limited warranty coverage, requiring proper installation documentation and compliance with outlined service and maintenance requirements to maintain full warranty eligibility.

Prime the oiling system before startup and follow the recommended Cummins break-in procedure using the correct oil and service interval schedule. Replace filters, flush the cooling system, and inspect turbochargers and intercoolers for contamination from any prior engine failure.

If the previous engine experienced internal damage, confirm intake and exhaust paths are free of debris that could compromise the replacement engine. Taking these preventative measures reduces the risk of premature wear and supports consistent lubrication and cooling performance from the start.

Monitor oil pressure and coolant temperatures during controlled warm-up cycles, then operate under light load before towing. Completing the initial service interval on time supports proper ring seating, stabilizes bearing surfaces, and helps protect warranty eligibility while improving long-term reliability and overall diesel engine performance. Careful adherence to these steps ensures dependable operation and maximizes the service life of your replacement engine.

Our team assists with lead times, Cummins core return handling, and technical guidance to keep the engine replacement process efficient from delivery through startup, ensuring proper compliance, streamlined logistics, and reliable performance for your diesel engine installation.

Freight process and core return

Engines ship on reinforced pallets with protective wrapping, banding, and corner guards to prevent transit damage. Dock and lift-gate delivery options are available depending on carrier access at your location, ensuring safe and secure transportation of your diesel engine.

Cores must be fully drained and returned using the provided RMA and BOL within the approved return window. Reuse the shipping crate and secure the core with straps and bracing to prevent movement during transport and reduce the risk of damage.

Refunds are processed after inspection. Missing components, cracks, contamination, or improper packaging may reduce credit value. Reviewing the Cummins core return checklist before shipment helps protect your refund and ensures a smooth, timely reimbursement process.
